Imagine seeing someone collapse in cardiac arrest. What would you do? What should you do? Rather than offer a CPR video, the agency created a site that shows the reaction of people in a mall to just such an event. The interactive video asks users to choose an action. The simulator has racked up 2.5 million uniques, half of them organic, and is being used throughout the world to educate people on what to do if YOU go down in the street.
